A crude approximation of voice production is to consider the breathing passages and mouth to be a resonating tube closed at one end. What is the fundamental frequency f1 if the tube is 0.240 m long, by taking air temperature to be 37.0∘C?

A 38.0-Hz sound wave is barely audible at a sound intensity level of 60.0 dB. The density of air at 20.0°C is 1.20 kg/m3. Speed of sound in air at 20.0°C is 343 m/s. What is the displacement amplitude of a 38.0-Hz sound wave? What is the ratio of the displacement amplitude to the average distance between molecules in air at room temperature, about 3.00 nm?

Describe how you would calculate the wavelengths of sounds at the extremes of the audible range, 20 and 20,000 Hz, in 60.0°C air. (Assume that the frequency values are accurate to two significant figures.)

A pipe open at both ends has a fundamental frequency of 300 HZ when the temperature is 0C if the speed of sound in air is 331M/S at 0C what is the length of the pipe? What would be the frequency of the fundamental as the temperature increases to 20 C where the speed of sound is 343M/S?
